Good To Know

Q: Is this an original Sea-Doo part? A: No, it is an aftermarket oil pump cover made for Sea-Doo models and cross-referenced to OEM part number 420811591. Q: What should I check before ordering? A: Confirm your engine is the 1503 and that your model year falls between 2008 and 2019 so the cover mates correctly to the oil pump.
